What is channeling?
I tend to believe this is just a normal spiritual function. We channel energy all the time. We can also communicate with those that aren't with us physically. Our guides for example, they communicate threw a verity of methods, and we channel that information. We are conduits for light, and those of light (our guides). If we take our brains out of the equation, we have better clarity. We're not going crazy when we hear those voices in our heads, or when we feel compelled to do things that don't make sense to us at the time. My guides had to trick me for many years by using my own voice, as our higher selves often do. I read that it was dangerous, and that closed my mind for too long. I now find that the danger is not knowing you have control over your own vessel, and you chose to whom you wish to interchange, or communicate to. I personally choose light, and that's it, danger gone. When we open up and "listen", the universe has a lot to offer, and we can make that jump!! The universe has a since of humor, and you'd be surpassed at who might be laughing with you.
Healing comes threw these means. Also a big part of this is letting go so "god" can flow threw us. Trust often becomes an issue, or at least it did with me. My brain wanted so bad to be in control all the time. I found it very hard to trust what I felt to be right. Letting go to trust your higher faculties can be hard at first, but like anything else with practice over time the brain will learn. Remember one must heal thyself. Sometimes I think of it as pushing the barrier to the next step. Crush the tower to revel the truth, not just a bunch of claims the brain needs to sustain it's illusion. We are all part of the big picture, and it is part of us. Every one of us is the universe as it is every one of us. Some times we forget what we are, and that's the real barrier. I think of it as trying to match this reflection to the next and so on. Healing is just a matter of channeling the energy from "god" that heals.
Learning to channel our guides. This is really a personal thing. We are all different, and we all have been shaped by our past. Our experience is different, and we do things differently. Every individual has there own unique perspective. So I suggest really looking at yourself, and follow your heart about what feels conferrable to you. It's very likely you have shared part of your past with your guides. They probably speak your "cosmic language". And normally the birds of a feather rule applies.
I've worked with a number of people helping them communicate with their guides. Let me use my mom as an example. She has spent many lives here as an American Indian, and mostly in the Cherokee tribe. She's been collecting native American art for years. She's traced her bloodline back to the Cherokee tribe, and a number of other things that gave the clues. Her main guide is of course a tribal medicine man. My point is if it feels right it probably is.
Brains like to have things in there language too. For example, my "cosmic language" is the code found on the carrier wave, or matrix (it's encoded information found). So for years that was my channeled communication, I knew it was happening, but it was so far into my subconscious I really didn't understand what was going on. My brain likes English, it likes to see pictures that look like things we have here on earth. Bringing things to the consciousness, and our awareness will increase. The brain can be taught to understand things on a broader scope. The spirit can be taught to translate, or whatever needs to happen for better communications. And this is just my perspective too, and there are many. I encourage you to look into as many as you can, and see what feels right to you. There are so many light beings around, and they all have things to teach us. They love it when we can communicate with them on a level they can be "heard" with clarity.
The universe communicates with us all the time, but are we "listening"? Like many of you, I have days I do and days I don't. The day's I do seem to fall into place. I feel compelled to say, or do something, and I do. And I'm not talking about listening to the brain either, listening with it is a better use for the brain. Looking into the clouds, and the message is clear. The universe communicates on so many levels. Personally I'd rather be tuned in, and learning threw it than not. And believe me being in these human vessels, there are going to be those days when it's harder to do than others. Just like working out a mussel, the more you work it, the stronger it gets. If only we came equipped with an answering service to record these messages.
Channeling is about communication. It's about letting go. You can let go to the point where you are having conversations with entities, or even have them use your body. Personally I don't just let any entity have control of my body, but that's also a personal thing. I have a dragon that has as much control of my body as it wants. I decided this however before I was even born, and I didn't even let it happen until I remembered that this lifetime. Some people let a wide verity of entities inhabit there body, or communicate with them. Some only the ones there guides deem able.

I think you will find that when you communicate with your guides on a telepathic level you will reach your spiritual in a clear concise manner. It all starts with opening your heart and mind.
